The Springfield Armory Agency Optic System (AOS) Mounting Plate – 1911 DS for HEX Dragonfly, Black (PH5077N-DRAG-PLATE-RET) is a purpose-built optic interface designed to give your double-stack Springfield 1911 DS a rock-solid, low-profile mounting solution for the HEX Dragonfly red dot sight. If you’re running one of Springfield’s modern double-stack 1911s with the Agency Optic System slide cut, this plate is the factory-correct way to add their flagship optic with flawless fit and reliable zero retention.
Precision-Matched for 1911 DS Agency Optic System Slides
This AOS mounting plate is specifically engineered for Springfield Armory 1911 DS pistols that feature the Agency Optic System cut.
Direct fit to Springfield 1911 DS AOS slides
Correct optic pattern for HEX Dragonfly red dot sights
Maintains a low, clean profile that complements the slide lines
Instead of relying on aftermarket adapter plates, this factory-spec solution ensures your Dragonfly optic sits at the correct height and angle, helping you co-witness with appropriate-height sights (if equipped) and maintain a consistent presentation.
Designed for HEX Dragonfly Red Dot
Springfield built this plate as a dedicated interface for their own HEX Dragonfly optic footprint.
Benefits of a dedicated Dragonfly plate:
No guesswork on footprint compatibility – it’s made specifically for the HEX Dragonfly
Provides full support and proper engagement for the optic’s recoil lugs and screws
Helps the optic track true under recoil, maintaining zero and preventing shifting
If you’ve invested in a Dragonfly, this is the plate that lets it perform as intended on your 1911 DS.
Rock-Solid, Duty-Ready Construction
The AOS mounting plate is built with durability in mind, suitable for defensive carry, competition, or training:
Robust metal construction (tough enough for high-round-count pistols)
Designed to seat tightly into the AOS pocket for maximum surface contact
Resists loosening and shifting under the repeated impulse of .45 ACP or 9mm double-stack loads
When properly installed with thread-locker and torqued to spec, this plate delivers the kind of stability you need on a serious-use pistol.
Low Profile for Faster Sight Acquisition
One of the biggest advantages of a dedicated AOS plate is the low mounting height it provides:
Keeps the optic lower to the bore, improving natural point-of-aim
Helps with a more intuitive, “heads-up” shooting style using the dot
Can make finding the dot faster during draws, transitions, and follow-up shots
For competition shooters and defensive users alike, a lower, more integrated optic mount is a real performance advantage over tall, stacked adapter systems.
Clean Black Finish – Matches 1911 DS Slides
The black finish on this mounting plate is chosen to match the aesthetic of Springfield’s 1911 DS slides:
Matte black appearance blends with the slide and optic
Helps avoid distracting reflections or glare
Gives the pistol a factory-integrated, professional look instead of a mismatched aftermarket stack
If you care about both performance and appearance, this plate ensures your Dragonfly install looks as good as it runs.
Simple Installation with Factory-Correct Geometry
Installing the Springfield AOS Dragonfly plate is straightforward for anyone familiar with optics-ready pistols:
Remove the existing AOS cover plate from your 1911 DS slide.
Clean mounting surfaces and apply appropriate thread-locker to the included screws (follow Springfield’s instructions).
Install the PH5077N-DRAG-PLATE-RET plate into the AOS pocket, ensuring it seats fully.
Attach the HEX Dragonfly optic using the correct screws and torque values.
Because the plate is designed specifically for AOS cuts and the Dragonfly footprint, alignment is simple and repeatable.
Ideal for Duty, Defense, and Competition Builds
This 1911 DS AOS mounting plate for HEX Dragonfly is perfect for:
Defensive carry 1911 DS pistols where a rugged, dedicated optic interface is critical
Competition builds, where a solid mount and consistent zero are mandatory
Range and training pistols used to build modern red dot pistol skills
If your Springfield 1911 DS is optics-ready and you run—or plan to run—a HEX Dragonfly, this plate is the essential link between slide and sight.
